Okay... Does Ryzen really need that high frequency RAM? I saw 2666 for less cheaper.. And i used to own Fx8350 the only reason i change to 4570 is micro stutter, even it run 60 fps but i can still feel it stutter and not at 4570.. well when copying,extracting,rendering FX is more superior in my opinion.. does this happen to new Ryzen VS Sky/Kaby/Coffelake..

You'll be surprised how a Ryzen processor on 2400Mhz RAM doesn't push GPU as good as a 3200Mhz RAM.

Even an overclocked Ryzen on 2400Mhz doesn't perform as a stock Ryzen on 3200Mhz when it comes to pushing GPU.

I'm using GTX 1080 also still game on 1080p, because I want high refresh rates.

That exactly what i mean... i don't even care if i got bottleneck (not massive) but fps beyond 60 for incoming games instead balance between CPU & GPU but strugle to keep 60fps... This bothering me alot..
